Tim Cook Steps Down as Apple CEO as John Ternus Prepares to Take Over

A planned leadership change places Cook in the executive chair with Ternus set to prioritize artificial intelligence before Apple’s Sept. 9 product event.

Overview

  • Tim Cook completed his final day as Apple CEO on Monday and sent employees a farewell memo saying he was deeply reassured to hand leadership to John Ternus.
  • John Ternus will become CEO on September 1 after more than two decades at Apple and is best known for leading the company’s hardware engineering work on iPhone, iPad, AirPods and other products.
  • Apple has formalized Cook’s move to executive chair and multiple reports say he will remain closely involved with company affairs and external relations, including meetings with global leaders.
  • Bloomberg reporting and company signals indicate Ternus will make artificial intelligence a top priority, and his first major public test will be Apple’s Sept. 9 product event, where new devices are widely expected though not yet confirmed by Apple.
  • Internal gestures such as a farewell party at Apple Park and employee anniversary plaques signed by Ternus reflect an orderly handover, and Cook’s 15-year run as CEO leaves Apple positioned by hardware and services strengths that Ternus must sustain and adapt for AI integration.
